Restore Full Electrical Function to Your GM Truck or SUV
Are you battling frustrating electrical gremlins in your GMC Yukon, Chevy Silverado, or Cadillac Escalade? Flickering lights, unresponsive power windows, a dead HVAC system, or a persistent security light are all classic signs of a failing Body Control Module (BCM).

Installation and Post-Install Procedures
The BCM is typically located under the driver’s side dashboard, near the steering column, making for a quick replacement that often takes less than 15 minutes. While the module is plug-and-play, some vehicles may require a ‘Setup SDM Primary Key in BCM’ procedure if the airbag light remains on after installation. This syncs the new BCM with the airbag system and can be done with a professional-grade scan tool. Additionally, a brake pedal position sensor relearn may be needed. There is no core charge for this part, so you can keep your old module without hassle.

Frequently Asked Questions
Do I need to have this BCM programmed by a dealer?
No. We pre-program the module to your vehicle’s specific VIN before shipping. It arrives ready for a plug-and-play installation, saving you time and money.
Where is the BCM located on my 2008 GMC Yukon?

Why is my airbag light on after installing the new BCM?
